62-11-00 4-2 DISASSEMBLY: ROTOR - TEETERING PARTS
GENERAL, REFERENCES AND REQUIREMENTS
Basic operational task, which can be performed by a licensed pilot or instructed personnel!
Rotor system must be removed, see
SPECIAL TOOLS AND CONSUMABLE MATERIALS
LR IMPORTANT NOTE: Procedure involves parts with limited reusability. Check Parts List below
before starting job!
PRECAUTIONS AND SAFETY MEASURES
WARNING: When handled incorrectly the rotor system can be damaged irreparably. If undetected this
may have catastrophic consequences!
CAUTION: The rotor hub must never be disassembled!
CAUTION: When removing or disassembling make sure to mark all parts so that each and every part of
the component is re-assembled and installed in exactly the same location and orientation!
PROCEDURES
1 To disassemble the rotor system, place it upside down onto a clean surface or stands to support the rotor at
approximately 2 m from the hub.
2 Unscrew and discard self-locking nuts (9) on the first blade by counter-holding the corresponding bolt head to
prevent it from turning.
3 Push out all shoulder bolts (1 - 5) without any force, but use no more than a gentle tapping if necessary. Tilt
the rotor blade up and down to support easy removal of the bolt
4 Carefully pull the rotor blade out of the hub (7) in radial direction and take off the clamping profile (10).
5 Repeat step 2 to 4 on second rotor blade.
IMPORTANT NOTE: Do not disassemble the rotor hub!
6 Place rotor blades, clamping profile and rotor hub in a suitable way to prevent bending or surface damage.
IMPORTANT NOTE: Do not lift or support the rotor system at its blade tips as the bending
moment due to the weight of the hub assembly may overstress the blade roots. If possible,
handle with two persons while holding approximately in the middle of each blade. When
supporting the system use two stands each positioned in about 2 meter distance from the
hub.
